' IMSI?JROV'EIVIEN'T` IN OIL-CANS.

The Schedule referred td in these Letters Patent making of the same.

To all whom it may concern Be it known that I, PATRICK J. DwYER, of Elizabeth Port, in the county of Union and State of New Jersey, have invented a new and useful Improvement in Oil-Gans, of which the following is a full, clear, and exact description, reference being had to theaccompan ying drawing forming part of this specitication, and which represents'a longitudinal section of an oil-can constructed in accordance with my improvement.

This improvement relates to oil-cans, in which the oil is ejected by pressure of the thumb upon its bottom, that is made elastic for such purpose.

As these cans have heretofore been constructed, their durability has been but very limited, by reason of the elastic bottom soon wearingoutorbursting, while the body of the can remains perfectly sound; and as the bottom has heretofore been soldered to the body, and thereby made an integral part of the latter, the destruction of thc bottom has involved tbe ruin of the whole can, the necessary repair `in such case not Warranting the expense. l

My-invention yobviates this, by constructing the can so that its bottom is readily detachable, whereby, when one bottom is destroyed, the same may be easily removed and a new bottom inserted; and as such bot,- toms may be sold in sets together with the can, the sizes varying with Vthe different sized cans, the expense of providing for necessary repair of the can is but trilling.

Referring to the accompanying drawing- A represents the body of the can, and B, its spout or tube.

Vthin the body, preferably at some distance above its lower edge, is an internal annular flange, a, secured by solder or otherwise. v

Upon the under side of this ring I lay a Washer, b, made oi`-any suitable soft or compressible material;

' required.

and upon or under this, place the separate elastic bottom G, which is secured in its place, and its junction with the body made tight, by a flange-ring, D, having a screw-thread on its exterior, and made to [it a female thread in the-lower portion 'of the body, a soft or compressible packing,-'c, preferably being inserted between the screw-ring and the bottom C. e

The ring D should be provided with ears or projections, l, to facilitate its being screwed in or out, as

An elastic bottom, which, as well as the bodyv of the can, may be made of any suitable material, thus separately fitted, is readily attachable and detachable, and, when in its place, secure against leakage. Instead of being elast-ic in itself, it may have an elastic action given to it, or its elastieitybe increased, by a spring, arranged within the body of the ean,which construction or provision the term elastic bottom is designed to include.

Bygiving the bottom a sunken position within the can, the same ispprotccted from injury, and a steadier 'bearing for the can insured in restingit on or sliding it over a bench o1' other surface.

What is here claimed, anddesired to be secured by Letters `Patent, is-

1.. A n oil-can, provided with a loose and readily detachable elastic bottom, for operation substantially as specified.

2. 'lhc combination and arrangement with the body A of the detachablebottom C, the packing or packings b c, and the screw-ring D, esscutiallyas and for the purposes 'herein set forth.
